Plexus (NASDAQ: PLXS) Q2 2026 revenue up 18.7% to $1.16B

Rhea-AI Filing Summary

Plexus Corp. delivered strong growth for the quarter ended April 4, 2026. Net sales rose to $1.16 billion from $980.2 million, an 18.7% increase, driven by higher demand across AMER, APAC and EMEA regions and all three market sectors.

Net income increased to $49.8 million from $39.1 million, with diluted EPS up to $1.82 from $1.41. Gross margin edged up to 10.2% and operating margin to 5.3%, helped by higher volumes and favorable mix despite higher fixed and compensation costs.

Cash generation weakened as operating cash flow fell to $13.1 million from $90.3 million, largely due to higher inventories and other working capital uses, resulting in free cash flow of negative $34.6 million. The company ended with $303.2 million in cash and $234.1 million of debt and spent $43.0 million repurchasing 262,092 shares, with $42.0 million remaining under its current buyback authorization.

Positive

• Strong top- and bottom-line growth: Quarterly net sales rose 18.7% to $1.16 billion, net income increased to $49.8 million, and diluted EPS climbed to $1.82, with modest margin expansion.
• Returns exceed cost of capital: Six-month after-tax ROIC of 13.8% versus a 9.0% WACC reflects continued positive economic return of 4.8% on invested capital.

Negative

• Weaker cash generation and higher working capital: Six-month operating cash flow fell to $13.1 million and free cash flow to $(34.6) million, driven by higher inventories, increased receivables and greater prepayments.

Insights

Equity analyst

Double-digit revenue and EPS growth, solid ROIC, but weaker free cash flow due to working capital build.

Plexus grew net sales 18.7% to $1,163.8 million, with broad-based strength across AMER, APAC and EMEA and its Aerospace/Defense, Healthcare/Life Sciences and Industrial sectors. Net income rose to $49.8 million and diluted EPS to $1.82, while gross and operating margins ticked higher to 10.2% and 5.3%.

Management reports $90.991 million in six-month net income and a non-GAAP after-tax ROIC of 13.8% versus a 9.0% WACC, implying positive economic return. However, six-month operating cash flow dropped to $13.1 million, with free cash flow at $(34.6) million as inventories grew and other assets increased.

The company ended the quarter with $303.2 million in cash and $234.1 million of debt, after net borrowings on its revolving credit facility and $43.0 million of share repurchases. Future filings may clarify whether inventory and receivable levels normalize as recent program ramps mature.

Return on Invested Capital financial

"We define ROIC as tax-effected operating income before restructuring and other charges divided by average invested capital"

A percentage that shows how effectively a company turns the money invested in its business—both borrowed funds and shareholders’ equity—into operating profit after taxes. It tells investors whether a company earns more from its core operations than it costs to fund those operations; think of it like the annual return you’d expect from renovating a rental property—higher percentages mean the company uses capital more efficiently and is more likely to create value for shareholders.

economic return financial

"For the six months ended April 4, 2026, ROIC of 13.8% reflects an economic return of 4.8%"

Economic return is the actual financial gain an investment or project delivers after paying all costs and accounting for lost opportunities, inflation, and taxes. Think of it like the net harvest from a field after you subtract seeds, labor and the value of other crops you could have grown; it tells investors whether money truly grew or would have been better used elsewhere. Investors use it to compare choices and decide if a venture creates real value.

free cash flow financial

"We define free cash flow ("FCF") as cash flow generated or used in operations less capital expenditures"

Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.

cash flow hedges financial

"The Company has cash flow hedges related to forecasted foreign currency obligations"

A cash flow hedge is an accounting label companies use when they enter financial contracts—like currency or interest-rate agreements—to protect expected future cash payments or receipts from unpredictable moves. For investors, it signals that the company is trying to smooth out future cash variability (think of locking in a price to avoid surprises), which can reduce reported profit swings but also means the company has exposure to derivative instruments and their associated risks.

global minimum tax financial

"effective tax rates... were higher... primarily due to the implementation of the global minimum tax"

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE THREE AND SIX MONTHS ENDED APRIL 4, 2026 AND MARCH 29, 2025

(Unaudited)

1.    Basis of Presentation

The accompanying Condensed Consolidated Financial Statements included herein have been prepared by Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). The accompanying Condensed Consolidated Financial Statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the condensed consolidated financial position of the Company as of April 4, 2026 and September 27, 2025, the results of operations and shareholders' equity for the three and six months ended April 4, 2026 and March 29, 2025, and the cash flows for the same six month periods.

The Company’s fiscal year ends on the Saturday closest to September 30. The Company also uses a "4-4-5" weekly accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. The first quarter of fiscal 2026 included 14 weeks while all other fiscal quarters presented herein included 13 weeks.

Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"), have been condensed or omitted pursuant to the SEC’s rules and regulations dealing with interim financial statements. However, the Company believes that the disclosures made in the Condensed Consolidated Financial Statements included herein are adequate to make the information presented not misleading. It is suggested that these Condensed Consolidated Financial Statements be read in conjunction with the Consolidated Financial Statements and notes thereto included in the Company’s 2025 Annual Report on Form 10-K.

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and notes thereto. The full extent to which current global events and economic conditions will impact the Company's business and operating results will depend on future developments that are highly uncertain and cannot be accurately predicted. The Company has considered information available as of the date of issuance of these financial statements and is not aware of any specific events or circumstances that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. Actual results could differ materially from these estimates.

Recently Issued Accounting Pronouncements Not Yet Adopted:

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09 Income Taxes (Topic 740), which requires enhanced disclosures for income taxes. Early adoption is permitted. The Company intends to adopt the guidance when it becomes effective in the fourth quarter of fiscal 2026. The Company is currently evaluating the impact that the updated standard will have on our financial statement disclosures.

In November 2024, the FASB issued ASU 2024-03 Disaggregation of Income Statement Expense (Subtopic 220-40), which requires disaggregated information about certain income statement expense line items. The guidance is effective for the Company beginning in fiscal 2028. Early adoption is permitted. The Company is currently evaluating the impact that the updated standard will have on its financial statement disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which removes references to project stages, and requires capitalization of software costs to begin when management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the intended function. The guidance is effective for fiscal years beginning after December 15, 2027, and interim periods within those annual reporting periods. The Company is currently evaluating the impact the adoption of the standard will have on our financial statement disclosures.

The Company does not believe that any other recently issued accounting standards will have a material impact on its Consolidated Financial Statements or apply to its operations.

3.    Debt, Finance Lease and Other Financing Obligations

						April 4, 2026						September 27, 2025
4.22% Senior Notes, due June 15, 2028						$	50,000					$	50,000

Less: current portion						(143,112)						(45,793)
Long-term debt, finance lease and other financing obligations, net of current portion						$	91,034					$	91,987

As of April 4, 2026, the Company was in compliance with covenants under all debt agreements.

During the six months ended April 4, 2026, the highest daily borrowing under the Company's 5-year senior unsecured revolving credit facility (referred to as the "Credit Facility") was $187.0 million; the average daily borrowings were $104.8 million. During the six months ended March 29, 2025, the highest daily borrowing was $52.0 million; the average daily borrowings were $34.8 million.

The fair value of the Company’s debt, excluding finance lease and other financing obligations, was $186.0 million and $89.0 million as of April 4, 2026 and September 27, 2025, respectively. The carrying value of the Company's debt, excluding finance lease and other financing obligations, was $187.0 million and $90.0 million as of April 4, 2026 and September 27, 2025, respectively. If measured at fair value in the financial statements, the Company's debt would be classified as Level 1 in the fair value hierarchy. Refer to Note 4, "Derivatives and Fair Value Measurements," for further information regarding the Company's fair value calculations and classifications.

4.    Derivatives and Fair Value Measurements

All derivatives are recognized in the accompanying Condensed Consolidated Balance Sheets at their estimated fair value. The Company uses derivatives to manage the variability of foreign currency obligations. The Company has cash flow hedges related to forecasted foreign currency obligations, in addition to non-designated hedges to manage foreign currency exposures associated with certain foreign currency denominated assets and liabilities. The Company does not enter into derivatives for speculative purposes.

8

Table of Contents

The Company designates some foreign currency exchange contracts as cash flow hedges of forecasted foreign currency expenses. Changes in the fair value of the derivatives that qualify as cash flow hedges are recorded in "Accumulated other comprehensive income" in the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of the cash flows. In the next twelve months, the Company estimates that $6.4 million of unrealized gains, net of tax, related to cash flow hedges will be reclassified from other comprehensive (loss) income into earnings. Changes in the fair value of the non-designated derivatives related to recognized foreign currency denominated assets and liabilities are recorded in "Miscellaneous, net" in the accompanying Condensed Consolidated Statements of Comprehensive Income.

The Company enters into forward currency exchange contracts for its operations in certain jurisdictions in the AMER and APAC segments on a rolling basis. The Company had cash flow hedges outstanding with a notional value of $276.0 million as of April 4, 2026, and a notional value of $249.4 million as of September 27, 2025. These forward currency contracts fix the exchange rates for the settlement of future foreign currency obligations that have yet to be realized. The total fair value of the forward currency exchange contracts was a $6.4 million asset as of April 4, 2026, and a $10.1 million asset as of September 27, 2025.

The Company had additional forward currency exchange contracts outstanding with a notional value of $150.8 million as of April 4, 2026, and a notional value of $172.8 million as of September 27, 2025. The Company did not designate these derivative instruments as hedging instruments. The net settlement amount (fair value) related to these contracts is recorded on the Condensed Consolidated Balance Sheets as either a current or long-term asset or liability, depending on the term, and as an element of "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income. The total fair value of these derivatives was a $2.2 million liability as of April 4, 2026, and a less than $0.1 million liability as of September 27, 2025.

Fair Value Measurements:

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses quoted market prices when available or discounted cash flows to calculate fair value. The accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The input levels are:

Level 1: Quoted (observable) market prices in active markets for identical assets or liabilities.

Level 2: Inputs other than Level 1 that are observable, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability.

The following table lists the fair values of the Company’s derivatives as of April 4, 2026 and September 27, 2025, by input level:

Fair Value Measurements Using Input Levels Asset (in thousands)
Fiscal period ended April 4, 2026						Level 1						Level 2						Level 3						Total

Foreign currency forward contracts						$	—					$	4,226					$	—					$	4,226
Fiscal period ended September 27, 2025
Derivatives
Foreign currency forward contracts						$	—					$	10,110					$	—					$	10,110

The fair value of foreign currency forward contracts is determined using a market approach, which includes obtaining directly or indirectly observable values from third parties active in the relevant markets. Inputs in the fair value of the foreign currency forward contracts include prevailing forward and spot prices for currency.

5.    Income Taxes

Income tax expense for the three and six months ended April 4, 2026 was $8.1 million and $17.9 million, respectively, compared to $6.0 million and $12.2 million for the three and six months ended March 29, 2025, respectively.

The effective tax rates for the three and six months ended April 4, 2026 were 13.9% and 16.5%, respectively, compared to the effective tax rates of 13.2% and 13.8% for the three and six months ended March 29, 2025, respectively. The effective tax rates for the three and six months ended April 4, 2026 were higher than the effective tax rates for the three and six months ended March 29, 2025 primarily due to the implementation of the global minimum tax across several jurisdictions in which the Company operates.

The amount of unrecognized tax benefits recorded for uncertain tax positions decreased by $0.8 million for the three months ended April 4, 2026. The Company recognizes accrued interest and penalties on uncertain tax positions as a component of income tax expense. The amount of interest and penalties recorded for the three and six months ended April 4, 2026 were $0.1 million and $0.2 million, respectively.

Within the next 12 months, it is reasonably possible that federal, state and foreign tax audit resolutions could reduce unrecognized tax benefits by approximately $2.8 million, either because the Company’s tax positions are sustained on audit, the Company agrees to their disallowance or the statute of limitations closes.

The Company maintains valuation allowances when it is more likely than not that all or a portion of a net deferred tax asset will not be realized. During the three months ended April 4, 2026, the Company continued to record a full valuation allowance against its net deferred tax assets in certain jurisdictions within the EMEA and APAC segments and a partial valuation allowance against its net deferred tax assets in certain jurisdictions within the AMER segment, as it was more likely than not that these assets would not be fully realized based primarily on historical performance. The Company will continue to record a valuation allowance against its net deferred tax assets in each of the applicable jurisdictions going forward until it determines it is more likely than not that the deferred tax assets will be realized.

6.    Earnings Per Share

The following is a reconciliation of the amounts utilized in the computation of basic and diluted earnings per share for the three and six months ended April 4, 2026 and March 29, 2025 (in thousands, except per share amounts):

						Three Months Ended												Six Months Ended
						April 4, 2026						March 29, 2025						April 4, 2026						March 29, 2025
Net income						$	49,809					$	39,073					$	90,991					$	76,340
Basic weighted average common shares outstanding						26,757						27,109						26,762						27,098
Dilutive effect of share-based awards and options outstanding						553						553						607						628

Basic						$	1.86					$	1.44					$	3.40					$	2.82
Diluted						$	1.82					$	1.41					$	3.32					$	2.75

For the three months ended April 4, 2026, share-based awards of 0.1 million shares were not included in the computation of diluted earnings per shares as they were antidilutive awards. For the six months ended April 4, 2026 as well as the three and six months ended March 29, 2025, share-based awards of less than 0.1 million shares were not included in the computation of diluted earnings per share as they were antidilutive awards.

See also Note 12, "Shareholders' Equity," for information regarding the Company's share repurchase plans.

7.    Leases

The components of lease expense for the three and six months ended April 4, 2026 and March 29, 2025 indicated were as follows (in thousands):

						Three Months Ended												Six Months Ended
						April 4, 2026						March 29, 2025						April 4, 2026						March 29, 2025
Finance lease expense:
Amortization of right-of-use assets						$	1,203					$	1,374					$	2,508					$	2,731
Interest on lease liabilities						1,326						1,275						2,928						2,701
Operating lease expense						2,606						2,610						5,414						5,194

Total						$	6,041					$	6,779					$	13,253					$	13,054

Based on the nature of the right-of-use ("ROU") asset, amortization of finance lease ROU assets, operating lease expense and other lease expense are recorded within either cost of goods sold or selling and administrative expenses and interest on finance lease liabilities is recorded within interest expense on the Condensed Consolidated Statements of Comprehensive Income. Other lease expense includes lease expense for leases with an estimated total term of twelve months or less and variable lease expense related to variations in lease payments as a result of a change in factors or circumstances occurring after the lease possession date.

9.    Litigation

The Company is party to lawsuits in the ordinary course of business. We record provisions in the consolidated financial statements for pending legal matters when we determine that an unfavorable outcome is probable and the amount of the loss can be reasonably estimated.

Management does not believe that any such proceedings, individually or in the aggregate, will have a material positive or adverse effect on the Company’s consolidated financial position, results of operations or cash flows. However, legal proceedings and regulatory and governmental matters are subject to inherent uncertainties, and unfavorable rulings or other events could occur. Unfavorable resolutions could involve substantial fines, civil or criminal penalties, and other expenditures.

10.    Reportable Segments

Reportable segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (CODM) in assessing performance and allocating resources. The Company uses an internal management reporting system, which provides important financial data to evaluate performance and allocate the Company’s resources on a regional basis. Net sales for the segments are attributed to the region in which the product is manufactured or the service is performed. The services provided, manufacturing processes used, class of customers serviced and order fulfillment processes used are similar and generally interchangeable across the segments. A segment’s performance is evaluated based upon its segment income. Segment income includes its net sales less cost of sales and selling and administrative expenses, but excludes corporate and other expenses. Corporate and other expenses primarily represent corporate selling and administrative expenses, and restructuring costs and other charges, if any. Inter-segment transactions are generally recorded at amounts that approximate arm’s length transactions. The accounting policies for the segments are the same as for the Company taken as a whole. The CODM for the Company is the chief executive officer. The CODM uses

income generated from each segment in evaluating segment performance and whether to reinvest profits or allocate resources into the corresponding segment, in addition to long-term growth potential and other qualitative factors. Segment income is used to monitor budget versus actual results.

11.    Guarantees

The Company offers certain indemnifications under its customer manufacturing agreements. In the normal course of business, the Company may from time to time be obligated to indemnify its customers or its customers’ customers against damages or liabilities arising out of the Company’s negligence, misconduct, breach of contract, or infringement of third-party intellectual property rights. Certain agreements have extended broader indemnification, and while most agreements have contractual limits, some do not. However, the Company generally does not provide for such indemnities and seeks indemnification from its customers for damages or liabilities arising out of the Company’s adherence to customers’ specifications or designs or use of materials furnished, or directed to be used, by its customers. The Company does not believe its obligations under such indemnities are material.

In the normal course of business, the Company also provides its customers a limited warranty covering workmanship, and in some cases materials, on products manufactured by the Company. Such warranty generally provides that products will be free from defects in the Company’s workmanship and meet mutually agreed-upon specifications for periods generally ranging from 12 to 24 months. The Company’s obligation is generally limited to correcting, at its expense, any defect by repairing or replacing such defective product. The Company’s warranty generally excludes defects resulting from faulty customer-supplied components, design defects or damage caused by any party or cause other than the Company.

The Company provides for an estimate of costs that may be incurred under its limited warranty at the time product revenue is recognized and establishes additional reserves for specifically identified product issues. These costs primarily include labor and materials, as necessary, associated with repair or replacement and are included in the Company's accompanying Condensed Consolidated Balance Sheets in "other accrued liabilities." The primary factors that affect the Company’s warranty liability include the value and the number of shipped units and historical and anticipated rates of warranty claims. As these factors are impacted by actual experience and future expectations, the Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

Below is a table summarizing the activity related to the Company’s limited warranty liability for the six months ended April 4, 2026 and March 29, 2025 (in thousands):

			Six Months Ended
			April 4, 2026						March 29, 2025
Reserve balance, beginning of period			$	7,419					$	6,752
Accruals for warranties issued during the period			2,704						1,550
Settlements (in cash or in kind) during the period			(1,799)						(574)
Reserve balance, end of period			$	8,324					$	7,728

12.    Shareholders' Equity

On August 14, 2024, the Board of Directors approved a share repurchase program under which the Company was authorized to repurchase up to $50.0 million of its common stock (the "2025 Program"). The 2025 Program became effective upon completion of the 2024 Program and was completed in fiscal 2025. During the three months ended March 29, 2025, the Company repurchased 86,239 shares under this program for $12.2 million at an average price of $141.18 per share. During the six months ended March 29, 2025, the Company repurchased 171,062 shares under this program for $25.0 million at an average price of $146.14 per share. The three and six months ended March 29, 2025 purchased amounts exclude excise tax on share repurchases of $0.4 million.

On May 14, 2025, the Board of Directors approved a share repurchase program under which the Company is authorized to repurchase up to $100.0 million of its common stock (the “2026 Program”). The 2026 Program became effective upon completion of the 2025 Program and has no expiration. During the three months ended April 4, 2026, the Company repurchased 109,105 shares under this program for $20.6 million at an average price of $189.22 per share. During the six months ended April 4, 2026, the Company repurchased 262,092 shares under this program for $43.0 million at an average price of $164.20 per share. The three and six months ended April 4, 2026 purchased amounts exclude excise tax on share repurchases of $0.4 million. As of April 4, 2026, $42.0 million of authority remained under the 2026 Program.

All shares repurchased under the aforementioned programs were recorded as treasury stock.

13.    Trade Accounts Receivable Sale Programs

The Company has Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch (formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd.) (the "MUFG RPA"), HSBC Bank (China) Company Limited, Xiamen branch (the "HSBC RPA") and other unaffiliated financial institutions, under which the Company may elect to sell receivables; at a discount. All facilities are uncommitted facilities. The maximum facility amount under the MUFG RPA is $340.0 million. The maximum facility amount under the HSBC RPA is $70.0 million. The MUFG RPA will be automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA.

Transfers of receivables under the programs are accounted for as sales and, accordingly, receivables sold under the programs are excluded from accounts receivable on the Condensed Consolidated Balance Sheets and are reflected as cash provided by operating activities on the Condensed Consolidated Statements of Cash Flows. Proceeds from the transfer reflect the face value of the receivables less a discount. The sale discount is recorded within "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income in the period of the sale. The Company continues servicing receivables sold and performing all accounts receivable administrative functions, in exchange receives a servicing fee, under both the MUFG RPA and HSBC RPA. Servicing fees related to trade accounts receivable programs recognized during the six months ended April 4, 2026 and March 29, 2025 were not material.

The Company sold $223.3 million and $171.8 million of trade accounts receivable under these programs, or their predecessors, during the three months ended April 4, 2026 and March 29, 2025, respectively, in exchange for cash proceeds of $221.4 million and $170.1 million, respectively.

The Company sold $439.6 million and $323.0 million of trade accounts receivable under these programs, or their predecessors, during the six months ended April 4, 2026 and March 29, 2025, respectively, in exchange for cash proceeds of $435.9 million and $319.8 million, respectively.

As of April 4, 2026 and September 27, 2025, $236.1 million and $214.4 million, respectively, of accounts receivables sold under trade accounts receivable programs and subject to servicing by the Company remained outstanding and had not yet been collected.

14.    Revenue from Contracts with Customers

Revenue is recognized over time for arrangements with customers for which: (i) the Company's performance does not create an asset with an alternative use to the Company, and (ii) the Company has an enforceable right to payment, including reasonable profit margin, for performance completed to date. Revenue recognized over time is estimated based on costs incurred to date plus a reasonable profit margin. If either of the two conditions noted above are not met to recognize revenue over time, revenue is recognized following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying arrangement.

The Company recognizes revenue when a contract exists and when, or as, it satisfies a performance obligation by transferring control of a product or service to a customer. Contracts are accounted for when they have approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer.

The Company generally enters into a master services arrangement that establishes the framework under which business will be conducted. These arrangements represent the master terms and conditions of the Company's services that apply to individual orders, but they do not commit the customer to work with, or to continue to work with, the Company nor do they obligate the customer to any specific volume or pricing of purchases. Moreover, these terms can be amended in appropriate situations.

Customer purchase orders are received for specific quantities with predominantly fixed pricing and delivery requirements. Thus, for the majority of our contracts, there is no guarantee of any revenue to the Company until a customer submits a purchase order. As a result, the Company generally considers its arrangement with a customer to be the combination of the master services arrangement and the purchase order. Most of the Company's arrangements with customers create a single performance obligation as the promise to transfer the individual manufactured product or service is capable of being distinct.

17

Table of Contents

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. A performance obligation is satisfied over time if the Company has an enforceable right to payment, including a reasonable profit margin. Determining if an enforceable right to payment includes a reasonable profit margin requires judgment and is assessed on a contract-by-contract basis.

Generally, there are no subjective customer acceptance requirements or further obligations related to goods or services provided; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations are fulfilled.

The Company does not allow for a general right of return. Net sales include amounts billed to customers for shipping and handling and out-of-pocket expenses. The corresponding shipping and handling costs and out-of-pocket expenses are included in cost of sales. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from net sales.

Contract Costs

For contracts requiring over time revenue recognition, the selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company uses a cost-based input measurement of progress because it best depicts the transfer of assets to the customer, which occurs as costs are incurred during the manufacturing process or as services are rendered. Under the cost-based measure of progress, the extent of progress toward completion is measured based on the costs incurred to date.

Disaggregated Revenue

The table below includes the Company’s revenue for the three and six months ended April 4, 2026 and March 29, 2025 (in thousands):

						Three Months Ended												Six Months Ended
						April 4, 2026						March 29, 2025						April 4, 2026						March 29, 2025
Net sales:
Aerospace/Defense						$	212,218					$	172,516					$	390,149					$	332,246
Healthcare/Life Sciences						472,869						410,642						938,896						784,731

Total net sales						$	1,163,757					$	980,170					$	2,233,609					$	1,956,292

For the three and six months ended April 4, 2026 and March 29, 2025, approximately 85% of the Company's revenue was recognized as products and services transferred over time.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, contract assets and deferred revenue on the Company’s accompanying Condensed Consolidated Balance Sheets.

Contract Assets: For performance obligations satisfied at a point in time, billing occurs subsequent to revenue recognition, at which point the customer has been billed and the resulting asset is recorded within accounts receivable. For performance obligations satisfied over time as work progresses, the Company has an unconditional right to payment, which results in the recognition of contract assets. The following table summarizes the activity in the Company's contract assets during the six months ended April 4, 2026 and March 29, 2025 (in thousands):

						Six Months Ended
						April 4, 2026						March 29, 2025
Contract assets, beginning of period						$	150,654					$	120,560
Revenue recognized during the period						1,898,567						1,646,863
Amounts collected or invoiced during the period						(1,888,839)						(1,631,292)
Contract assets, end of period						$	160,382					$	136,131

18

Table of Contents

Deferred Revenue: Deferred revenue is recorded when consideration is received from a customer prior to transferring goods or services to the customer under the terms of the contract, which is included in advanced payments from customers on the Condensed Consolidated Balance Sheets. As of April 4, 2026 and September 27, 2025, the balance of advance payments from customers attributable to deferred revenue was $170.4 million and $151.3 million, respectively. The advance payment is not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect the company from the other party failing to adequately complete some or all of its obligations under the contract. Deferred revenue is recognized into revenue when all revenue recognition criteria are met. For performance obligations satisfied over time, recognition will occur as work progresses; otherwise, deferred revenue will be recognized based upon shipping terms.

end-market demand, an increase of $15.8 million due to production ramps for new customers and an increase of $15.1 million due to production ramps of new products for existing customers.

During the six months ended April 4, 2026, net sales in the Industrial sector increased $65.3 million, or 7.8%, as compared to the six months ended March 29, 2025. The increase in net sales was driven by overall net increased customer end-market demand, an increase of $24.4 million in production ramps of new products for existing customers and an increase of $18.5 million due to production ramps for new customers. The increase was partially offset by a decrease of $15.1 million due to a disengagement with a customer.

Cost of sales. Cost of sales for the three months ended April 4, 2026 increased $162.2 million, or 18.4%, as compared to the three months ended March 29, 2025, while cost of sales for the six months ended April 4, 2026 increased $250.5 million, or 14.3% as compared to the six months ended March 29, 2025. Cost of sales is comprised primarily of material and component costs, labor costs and overhead. For both of the three and six months ended April 4, 2026 and March 29, 2025, approximately 89% of the total cost of sales was variable in nature and fluctuated with sales volumes. Approximately 88% of these costs were related to material and component costs.

As compared to the three months ended March 29, 2025, the increase in cost of sales in the three months ended April 4, 2026 was primarily driven by an increase in net sales and an increase in fixed costs. As compared to the six months ended March 29, 2025, the increase in cost of sales in the six months ended April 4, 2026 was primarily driven by an increase in net sales and an increase in fixed costs.

Gross profit. Gross profit for the three months ended April 4, 2026 increased $21.4 million, or 21.9%, as compared to the three months ended March 29, 2025. Gross margin of 10.2% for the three months ended April 4, 2026 increased 20 basis points compared to the three months ended March 29, 2025. The primary driver of the increase in gross profit and gross margin was the increase in net sales, partially offset by an increase in fixed costs.

Gross profit for the six months ended April 4, 2026 increased $26.9 million, or 13.6%, as compared to the six months ended March 29, 2025. Gross margin of 10.1% for the six months ended April 4, 2026 remained flat compared to the six months ended March 29, 2025. The primary driver of the increase in gross profit was the increase in net sales, partially offset by an increase in fixed costs.

Operating income. Operating income for the three months ended April 4, 2026 increased $13.0 million, or 26.6%, as compared to the three months ended March 29, 2025. Operating margin of 5.3% for the three months ended April 4, 2026 increased 30 basis points compared to the three months ended March 29, 2025. The primary drivers of the increase in operating income and operating margin for the three months ended April 4, 2026 were the increase in gross profit and gross margin. The increase in operating income was partially offset by an increase of $8.4 million in selling and administrative expenses ("S&A"). The increase in S&A was primarily due to an increase in compensation costs.

Operating income for the six months ended April 4, 2026 increased $20.6 million, or 21.5%, as compared to the six months ended March 29, 2025. Operating margin of 5.2% for the six months ended April 4, 2026 increased 30 basis points compared to the six months ended March 29, 2025. The primary drivers of the increase in operating income and operating margin for the six months ended April 4, 2026 were the increase in gross profit as well as a decrease of $4.7 million in restructuring and other charges. The restructuring and other charges for the six months ended March 29, 2025 consisted of severance costs associated with a reduction in the Company's workforce in the EMEA and AMER regions. The increase in operating income was partially offset by an increase of $10.9 million in S&A. The increase in S&A was primarily due to an increase in compensation costs.

A discussion of operating income by reportable segment for the indicated fiscal period is presented below (in millions):

						Three Months Ended												Six Months Ended
						April 4, 2026						March 29, 2025						April 4, 2026						March 29, 2025

AMER. Operating income increased $11.8 million for the three months ended April 4, 2026 as compared to the three months ended March 29, 2025, primarily as a result of an increase in net sales, partially offset by a negative shift in customer mix, an increase in fixed costs and an increase in S&A.

During the six months ended April 4, 2026, operating income in the AMER segment increased $16.7 million as compared to the six months ended March 29, 2025, primarily as a result of an increase in net sales, partially offset by a negative shift in customer mix and an increase in fixed costs.

APAC. Operating income increased $11.5 million for the three months ended April 4, 2026 as compared to the three months ended March 29, 2025, primarily as a result of an increase in net sales and a positive shift in customer mix, partially offset by an increase in fixed costs.

During the six months ended April 4, 2026, operating income in the APAC segment increased $10.5 million as compared to the six months ended March 29, 2025, primarily as a result of an increase in net sales and a positive shift in customer mix, partially offset by an increase in fixed costs.

EMEA. Operating income increased $3.5 million for the three months ended April 4, 2026 as compared to the three months ended March 29, 2025, primarily as a result of an increase in net sales and a positive shift in customer mix, partially offset by an increase in fixed costs.

During the six months ended April 4, 2026, operating income in the EMEA segment increased $8.4 million as compared to the six months ended March 29, 2025, primarily as a result of an increase in net sales and a positive shift in customer mix, partially offset by an increase in fixed costs.

Other expense. Other expense for the three months ended April 4, 2026 increased $0.2 million compared to the three months ended March 29, 2025.

Other expense for the six months ended April 4, 2026 increased $0.3 million as compared to the six months ended March 29, 2025.

Income taxes. Income tax expense for the three and six months ended April 4, 2026 was $8.1 million and $17.9 million, respectively, compared to $6.0 million and $12.2 million for the three and six months ended March 29, 2025, respectively. The increase was primarily driven by the implementation of the global minimum tax across several jurisdictions in which we operate, as well as an increase in pre-tax book income.

Our annual effective tax rate varies from the U.S. statutory rate of 21.0% primarily due to the geographic distribution of worldwide earnings as well as a tax holiday granted to a subsidiary located in the APAC segment where we derive a significant portion of our earnings. Our effective tax rate may also be impacted by disputes with taxing authorities, tax planning activities, adjustments to uncertain tax positions and changes in valuation allowances.

The annual effective tax rate for fiscal 2026 is expected to be approximately 16.0% to 18.0% assuming no changes to tax laws.

Net income. Net income for the three months ended April 4, 2026 increased $10.7 million, or 27.4%, from the three months ended March 29, 2025 to $49.8 million. Net income increased primarily as a result of the increase in operating income, partially offset by the increase in tax expense as previously discussed.

Net income for the six months ended April 4, 2026 increased $14.7 million, or 19.3%, from the six months ended March 29, 2025 to $91.0 million. Net income increased primarily as a result of the increase in operating income, partially offset by the increase in tax expense as previously discussed.

Diluted earnings per share. Diluted earnings per share increased to $1.82 for the three months ended April 4, 2026 from $1.41 for the three months ended March 29, 2025, primarily as a result of increased net income due to the factors discussed above.

Diluted earnings per share increased to $3.32 for the six months ended April 4, 2026 from $2.75 for the six months ended March 29, 2025 primarily as a result of increased net income due to the factors discussed above.

Return on Invested Capital ("ROIC") and economic return. We use a financial model that is aligned with our business strategy and includes an ROIC goal of 15%, which would exceed our weighted average cost of capital ("WACC") by more than 500 basis points and represent positive economic return. Economic return is the amount our ROIC exceeds our WACC.

Non-GAAP financial measures, including ROIC and economic return, are used for internal management goals and decision making because such measures provide management and investors additional insight into financial performance. In particular, we provide ROIC and economic return because we believe they offer insight into the metrics that are driving management

decisions. We view ROIC and economic return as important measures in evaluating the efficiency and effectiveness of our long-term capital investments. We also use ROIC as a performance criteria in determining certain elements of compensation as well as economic return performance.

We define ROIC as tax-effected operating income before restructuring and other charges divided by average invested capital over a rolling three-quarter period for the second fiscal quarter. Invested capital is defined as equity plus debt and operating lease liabilities, less cash and cash equivalents. Other companies may not define or calculate ROIC in the same way. ROIC and other non-GAAP financial measures should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP").

We review our internal calculation of WACC annually. Our WACC is 9.0% for fiscal 2026 and 8.9% for fiscal 2025. By exercising discipline to generate ROIC in excess of our WACC, our goal is to create value for our shareholders. For the six months ended April 4, 2026, ROIC of 13.8% reflects an economic return of 4.8%, based on our WACC of 9.0%, and for the six months ended March 29, 2025, ROIC of 13.7% reflects an economic return of 4.8%, based on our WACC of 8.9%.

For a reconciliation of ROIC, economic return and adjusted operating income (tax-effected) to our financial statements that were prepared using U.S. GAAP, see Exhibit 99.1 to this Quarterly Report on Form 10-Q, which exhibit is incorporated herein by reference.

Refer to the table below, which includes the calculation of ROIC and economic return for the indicated fiscal period (dollars in millions):

						Six Months Ended
						April 4, 2026						March 29, 2025
Adjusted operating income (tax-effected)						$	193.1					$	174.6
Average invested capital						1,401.1						1,276.7
After-tax ROIC						13.8		%				13.7		%
WACC						9.0		%				8.9		%
Economic return						4.8		%				4.8		%

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents and restricted cash were $303.2 million as of April 4, 2026, as compared to $306.8 million as of September 27, 2025.

As of April 4, 2026, 83% of our cash and cash equivalents balance was held outside of the U.S. by our foreign subsidiaries. Based on current expectations, we believe that our projected cash flows provided by operations, available cash and cash equivalents, potential borrowings under the Credit Facility, and our leasing capabilities should be sufficient to meet our working capital and fixed capital requirements, as well as execute our share repurchase authorization as management deems appropriate, for the next twelve months.

Cash Flows. The following table provides a summary of cash flows (in millions):

Operating Activities. Cash flows provided by operating activities were $13.1 million for the six months ended April 4, 2026, as compared to cash flows provided by operating activities of $90.3 million for the six months ended March 29, 2025. The decrease was primarily due to cash flow improvements (reductions) of:

•$14.7 million increase in net income.

•$(170.7) million in inventory cash flows driven by an increase in inventory associated with ramping programs in the six months ended April 4, 2026 compared to a decrease in inventory driven by inventory reduction efforts in the six months ended March 29, 2025.

•$(56.4) million in accounts receivable cash flows driven by an increase in net sales as well as the timing of shipments and mix of customer payment terms.

•$(45.7) million in other current and non-current asset cash flows primarily driven by an increase in prepaid amounts owed to us by governmental entities for taxes and other governmental obligations in the six months ended April 4, 2026 as compared to the six months ended March 29, 2025 as well as an increase in prepayments to suppliers in the six months ended April 4, 2026 as compared to a decrease in the six months ended March 29, 2025.

•$85.4 million in advanced payments from customers cash flows as prior year had a significant outflow of deposit returns due to inventory management efforts.

•$76.0 million in accounts payables cash flows primarily driven by the timing of materials procurement and payments to suppliers.

•$6.0 million in other, net primarily driven by lower payments for operating leases in the six months ended April 4, 2026 compared to the six months ended March 29, 2025.

•$5.9 million in contract assets cash flows corresponding to changes in demand from over time customers.

The following table provides a summary of cash cycle days for the periods indicated (in days):

						Three Months Ended
						April 4, 2026						March 29, 2025
Days in accounts receivable						55						57
Days in contract assets						12						12
Days in inventory						120						132
Days in accounts payable						(74)						(70)
Days in advanced payments						(49)						(63)
Annualized cash cycle						64						68

We calculate days in accounts receivable and contract assets as each balance sheet item for the respective quarter divided by annualized sales for the respective quarter by day. We calculate days in inventory, accounts payable and advanced payments as each balance sheet line item for the respective quarter divided by annualized cost of sales for the respective quarter by day. We calculate annualized cash cycle as the sum of days in accounts receivable, days in contract assets and days in inventory, less days in accounts payable and days in advanced payments.

As of April 4, 2026, annualized cash cycle days decreased four days compared to March 29, 2025 due to the following:

Days in accounts receivable for the three months ended April 4, 2026 decreased two days compared to the three months ended March 29, 2025. The decrease is primarily attributable to the timing of customer shipments and payments as well as the mix of customer payment terms.

Days in contract assets for the three months ended April 4, 2026 remained flat compared to the three months ended March 29, 2025.

Days in inventory for the three months ended April 4, 2026 decreased twelve days compared to the three months ended March 29, 2025. The decrease is primarily attributable to increased net sales and continued inventory management efforts.

Days in accounts payable for the three months ended April 4, 2026 increased four days compared to the three months ended March 29, 2025. The increase is primarily attributable to timing of materials procurement and payments to suppliers.

Table of Contents

Days in advanced payments for the three months ended April 4, 2026 decreased fourteen days compared to the three months ended March 29, 2025. The decrease was primarily attributable to a return of advanced payments to customers due to continued inventory management efforts.

Free Cash Flow. We define free cash flow ("FCF"), a non-GAAP financial measure, as cash flow generated or used in operations less capital expenditures. FCF was $(34.6) million for the six months ended April 4, 2026 compared to $43.6 million for the six months ended March 29, 2025, a decrease of $78.2 million.

Non-GAAP financial measures, including FCF, are used for internal management assessments because such measures provide additional insight to investors into ongoing financial performance. In particular, we provide FCF because we believe it offers insight into the metrics that are driving management decisions. We view FCF as an important financial metric as it demonstrates our ability to generate cash and can allow us to pursue opportunities that enhance shareholder value. FCF is a non-GAAP financial measure that should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with GAAP.

A reconciliation of FCF to our financial statements that were prepared using U.S. GAAP as follows (in millions):

						Six Months Ended
						April 4, 2026						March 29, 2025
Cash flows provided by operating activities						$	13.1					$	90.3
Payments for property, plant and equipment						(47.7)						(46.7)
Free cash flow						$	(34.6)					$	43.6

Investing Activities. Cash flows used in investing activities were $47.7 million for the six months ended April 4, 2026 compared to $46.7 million for the six months ended March 29, 2025.

We currently estimate capital expenditures for fiscal 2026 will be approximately $100.0 million to $120.0 million to support new program ramps and replace older equipment.

Financing Activities. Cash flows provided by financing activities were $29.8 million for the six months ended April 4, 2026 compared to cash flows used in financing activities of $78.1 million for the six months ended March 29, 2025. The increase was primarily attributable to net borrowings on the credit facility for the six months ended April 4, 2026 of $97.0 million compared to net repayments on the credit facility for the six months ended March 29, 2025 of $35.0 million, partially offset by an increase of $18.1 million in cash used to repurchase our common stock.

On August 14, 2024, the Board of Directors approved a share repurchase program under which we were authorized to repurchase up to $50.0 million of our common stock (the "2025 Program"). The 2025 Program became effective upon completion of the 2024 Program and was completed in fiscal 2025. During the three months ended March 29, 2025, we repurchased 86,239 shares under this program for $12.2 million at an average price of $141.18 per share. During the six months ended March 29, 2025, we repurchased 171,062 shares under this program for $25.0 million at an average price of $146.14 per share. The three and six months ended March 29, 2025 purchased amounts exclude excise tax on share repurchases of $0.4 million.

On May 14, 2025, the Board of Directors approved a share repurchase program under which we are authorized to repurchase up to $100.0 million of our common stock (the “2026 Program”). The 2026 Program became effective upon completion of the 2025 Program and has no expiration. During the three months ended April 4, 2026, we repurchased 109,105 shares under this program for $20.6 million at an average price of $189.22 per share. During the six months ended April 4, 2026, we repurchased 262,092 shares under this program for $43.0 million at an average price of $164.20 per share. The three and six months ended April 4, 2026 purchased amounts exclude excise tax on share repurchases of $0.4 million. As of April 4, 2026, $42.0 million of authority remained under the 2026 Program.

All shares repurchased under the aforementioned programs were recorded as treasury stock.

We have Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch (formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd.) (the "MUFG RPA"), HSBC Bank (China) Company Limited, Xiamen branch (the "HSBC RPA") and other unaffiliated financial institutions, under which we may elect to sell receivables, at a discount. These facilities are uncommitted facilities. The maximum facility amount under the MUFG RPA as of April 4, 2026 is $340.0 million. The maximum facility amount under the HSBC RPA as of April 4, 2026 is $70.0 million. The MUFG RPA will be

automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA previously discussed.

We sold $223.3 million and $171.8 million of trade accounts receivable under these programs during the three months ended April 4, 2026 and March 29, 2025, respectively, in exchange for cash proceeds of $221.4 million and $170.1 million, respectively. We sold $439.6 million and $323.0 million of trade accounts receivable under these programs during the six months ended April 4, 2026 and March 29, 2025, respectively, in exchange for cash proceeds of $435.9 million and $319.8 million, respectively. As of April 4, 2026 and September 27, 2025, $236.1 million and $214.4 million, respectively, of accounts receivables sold under trade accounts receivable programs and subject to servicing by us remained outstanding.

In all cases, the sale discount was recorded within "Miscellaneous, net" in the Condensed Consolidated Statements of Comprehensive Income in the period of the sale. For further information regarding the receivable sale programs, see Note 13, "Trade Accounts Receivable Sale Programs," in Notes to Condensed Consolidated Financial Statements.

Based on current expectations, we believe that our projected cash flows provided by operations, available cash and cash equivalents, potential borrowings under the Credit Facility, and our leasing capabilities should be sufficient to meet our working capital and fixed capital requirements, as well as execution upon our share repurchase authorizations as management deems appropriate, for the next twelve months. We believe our balance sheet is positioned to support the potential future challenges presented by macroeconomic factors including increased working capital requirements associated with longer lead-times for components, increased component and labor costs, and operating inefficiencies due to supply chain constraints. As of the end of the second quarter of fiscal 2026, cash and cash equivalents and restricted cash were $303 million, while debt, finance lease and other financing obligations were $234 million. If our future financing needs increase, then we may need to arrange additional debt or equity financing. Accordingly, we evaluate and consider from time to time various financing alternatives to supplement our financial resources. However, we cannot be assured that we will be able to make any such arrangements on acceptable terms or at all.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

During the second quarter of fiscal 2026, there were no material changes in our exposure to market risk from changes in foreign exchange and interest rates from those disclosed in our 2025 Annual Report on Form 10-K.

Table of Contents

Foreign Currency Risk

Our international operations create potential foreign exchange risk. Our policy is to selectively hedge our foreign currency denominated transactions in a manner that partially offsets the effects of changes in foreign currency exchange rates. We typically use foreign currency contracts to hedge only those currency exposures associated with certain assets and liabilities denominated in non-functional currencies. Corresponding gains and losses on the underlying transaction generally offset the gains and losses on these foreign currency hedges. We cannot predict changes in currency rates, nor the degree to which we will be able to manage the impacts of currency exchange rate changes. Such changes could have a material effect on our business, results of operations and financial condition.

Our percentages of transactions denominated in currencies other than the U.S. dollar for the indicated periods were as follows: 

						Three Months Ended
						April 4, 2026						March 29, 2025
Net Sales						8%						10%
Total Costs						18%						16%

We have evaluated the potential foreign currency exchange rate risk on transactions denominated in currencies other than the U.S. dollar for the periods presented above. Based on our overall currency exposure, as of April 4, 2026, a 10.0% change in the value of the U.S. dollar relative to our other transactional currencies would not have a material effect on our financial position, results of operations, or cash flows.

Interest Rate Risk

We have financial instruments, including cash equivalents and debt, which are sensitive to changes in interest rates. The primary objective of our investment activities is to preserve principal while maximizing yields without significantly increasing market risk. To achieve this, we limit the amount of principal exposure to any one issuer.

As of April 4, 2026, our only material interest rate risk was associated with our Credit Facility. Borrowings under the Credit Facility bear interest, at the Company's option, at (a)(1) for borrowings denominated in U.S. dollars, the Term Secured Overnight Financing Rate ("SOFR"), (2) for borrowings denominated in pounds sterling, the Daily Simple Risk-Free Rate, plus, in each case of (a)(1) and (2), 10 basis points, (b) for borrowings denominated in euros, the EURIBOR Rate plus a statutory reserve rate, or (c) an Alternate Base Rate equal to the highest of (i) 100 basis points per annum, (ii) the prime rate last quoted by The Wall Street Journal (or, if not quoted, as otherwise provided in the Credit Facility), (iii) the greater of the federal funds effective rate and the overnight bank funding rate in effect on such day plus, in each case, 50 basis points per annum (or, if neither are available, as otherwise provided in the Credit Facility), and (iv) Term SOFR for a one month interest period on such day plus 110 basis points, plus, in each case of (a), (b), and (c), an applicable interest rate margin based on the Company's then current consolidated total indebtedness (minus certain unrestricted cash and cash equivalents in an amount not to exceed $100 million) to consolidated EBITDA. As of April 4, 2026, the borrowing rate under the Credit Facility was SOFR plus 1.00%. Borrowings under the 2018 NPA are based on a fixed interest rate, thus mitigating much of our interest rate risk. Based on our overall interest rate exposure, as of April 4, 2026, a 10.0% change in interest rates would not have a material effect on our financial position, results of operations, or cash flows.

ITEM 4.    CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure that the information the Company must disclose in its filings with the Securities and Exchange Commission ("SEC") is recorded, processed, summarized and reported on a timely basis.
